This introduction is reported to work with Ubuntu 7.04/6.10/6.06 on multiple setups

Note: enabling TwinView breaks suspend-to-ram (reported to work with drivers 96XX), if you know better please delete this note and write how you did it ~ Bernstein See also: https://launchpad.net/bugs/34043 First: update your /etc/X11/xorg.conf and add an "Option "NvAGP" "1" line in the "Section "Device"  :

Section "Device"
        ...
        Option          "NvAGP"       "1"
EndSection

This bug is tracked at https://launchpad.net/bugs/34043. Second: disable warm-booting the video hardware on resume by editing your /etc/default/acpi-support as follows:

...

# Should we attempt to warm-boot the video hardware on resume?
POST_VIDEO=false

...

(Note: On Gutsy, POST_VIDEO only affects suspend, not hibernate.) You should also disable the SAVE_VBE_STATE option, if it set in your file:

SAVE_VBE_STATE=false

If you don't have a suspend option, you need to manually enable ACPI_SLEEP in the same file. However, this should be enabled by default. Third: If you're running 7.10 (gutsy) and you're using compiz (desktop-effects) in conjunction with NVIDIA binary drivers, make sure your "Sync to VBLANK" option in "Advanced Desktop Effects Settings > General > Display settings" is *disabled*. You can set this option to false by running: gconftool --set /apps/compiz/general/screen0/options/sync_to_vblank 0 --type bool Unless this setting is set to false, the graphical interface (X11) tends to wake up with just a blank screen (possibly with a working mouse cursor).
